Description
This parameter is used to configure the thermal constant of the motor coil, which is the break
frequency of a single-pole low-pass filter model of the thermal dynamics of the motor coil.
This parameter, together with MOTOR.IPEAK (pg 383) and MOTOR.ICONT (pg 380), deter-
mine the motor foldback parameters IL.MFOLDD (pg 362),IL.MFOLDT (pg 362), and
IL.MFOLDR (pg 362).
Calculating MOTOR.CTF0
Given a motor coil/winding thermal time constant T in seconds, then:
MOTOR.CTF0 = 1/(2πT)
